Crystal golems are small golems, created by gnomes. They are typically 4’ tall and made of a hard clear crystalline substance. Each crystal golem is made with a separate controlling crystal, which looks like a piece of quartz. This controlling crystal is often attached to a heavy necklace. The owner of the crystal controls the golem and that person is able to give simple instructions to the golem. Gnomes are able to successfully control the golem while possessing the controlling crystal. For other races possessing the controlling crystal, there is a 1 in 6 chance that the golem will not carry out each command.
COMBAT: Crystal golems use their tiny crystalline fists in combat, getting two attacks per round. They attack as 5 hit dice creatures.
MAGIC IMMUNITY: Crystal golems are immune to most forms of magic. They take normal damage from electrical-based spells and are also subject to damage from fire-based spells (see below).
FIRE IMMUNITY/RESISTANCE: Crystal golems are immune to normal fire and gain a +4 to saving throws versus magical fire. They take half damage from fire-based spells and other forms of magical fire.
IMMUNE TO NON-MAGICAL WEAPONS: Crystal golems are immune to non-magical weapons. They are not immune from attacks from “outsiders,” such as dragons, fey, and demons, although they do gain a +2 armor class bonus against such creatures.
